Smart Keys For Cars Smart keys are wireless remotes that can open doors and open the trunk without the necessity of a traditional mechanical blade. It is also able to start the car without turning the key. smart car key fob of smart keys have battery indicators that alert you to the low battery well in advance. It's easy to replace the battery without any special tools. Convenience Smart keys are able to unlock doors and trunks as well as turn on the engine of the car without the driver having to use a metal key. They also have features that are designed to prevent burglaries and vehicle thefts, such as a panic button, which generates noise to scare away people who might be a threat to thieves or in areas with no security like underground garages that are parking. These key fobs do all these things by sending radio signals between the car and the key fob, using low-power wireless technology. This is a wonderful option for those on the move and don't have a lot of time. A smart key is usually designed to look more like a plastic card than a key, and can be used to open the trunk or car's doors when the fob's button is pressed. Some even have built-in touchscreens that allow drivers to control certain settings on their vehicle, such as audio and climate. The RFID signal that is transmitted between a key fob and car is unique, encoded and tied to the car's onboard computer. This makes it nearly impossible for criminals with a technological background to connect a stolen car equipped with a key fob. These key fobs can be programmed to transmit a new frequency signal every time they're used, so the computer onboard won't recognize an old one as the “true” signal. Security Many people aren't keen to make the switch to digital car keys due to the fact that they worry about security. While having a physical key fob at hand might feel more secure the digital keys are more secure than the majority of people think. Digital keys are secure and the signal they transmit to a car is verified by an onboard computer. This means that even if your smart key fob is compromised the car will not start. Smart keys unlike traditional key fobs, function by using the built-in antennas of your car to connect with it and perform basic functions like unlocking and starting your vehicle. This allows you to gain access to your vehicle without a physical key inserted into the ignition or lock. Many systems offer an alternative method of opening and starting your car in the event that you lose your smartkey, or if the battery goes out. Emergency starting can be achieved by inserting the key into a slot or holding it close to an area of the cockpit where an inductive coil could transfer energy. The majority of smart keys come with a low battery indicator, which warns you before the key is dead. You can easily replace the battery on your own when you need to. Auto-adjusting settings Instead of a physical key instead, the smart key makes use of radio waves to unlock and lock the vehicle. The smart key is also able to remotely start the engine and monitor your vehicle's location in case you don't remember where you parked it. Some smart keys have settings that automatically adjust the vehicle's exterior and interior based on the key you've chosen to use. The car can adjust the position of the seat and mirror settings, as well as the temperature control based on the type of key used. This is beneficial if you have multiple drivers or wish to limit certain features when you lend your car to a new driver. Smart keys also have the benefit of using encryption to prevent theft. This is not a possibility with traditional keys. This technology makes it difficult for tech-savvy criminals to steal a car by mimicking a valid frequency according to How Stuff Works Electronics. Smart keys send a unique encrypted message each time the vehicle's remote is unlocked. Just like any other battery-powered device the battery of a smart keys will eventually be depleted of power. The majority of systems have backup systems to unlock the car and begin it if the battery is not able to function. The emergency method varies, but usually involves either holding the key within range of the car's lock sensor or pressing the button on the key which activates the emergency starter. Battery backup Modern smart keys, which are also known as keyless entry systems or passive entry, utilize a transmitter and a receiver to unlock your vehicle. The transmitter is incorporated into the key fob that you carry around with you, and the receivers are placed within your car and around the outside. When you get close to the vehicle the radio frequency signal from your smart key is picked up by the receivers, and it activates the doors and ignition. While this system offers many advantages, including the ability to not have to search in the dark to find the key, it can be vulnerable to certain kinds of attacks. For instance, if your key's battery is damaged or is stolen, a third party could be able to pick up the low frequency transmission signals from your key and open your car, reports How Stuff Works Electronics. This is why the majority of smart keys feature encrypted signals to make hacking a challenge. However, these systems may also be impacted through electromagnetic fields created by cell phones, computers and other devices. If you find that your smart key fob is not functioning properly, it could be due to an interference problem. In this case it is advised not to place your keys near devices like these until the battery in the fob has been replaced. The majority of smart keys will notify you when their batteries are depleted and the replacement process is relatively simple.
